Exceptions

CouldNotProcessData template

Template for an exception that indicates that the data could not be processed.

interface ImageResizerException extends Throwable {}

final class ImageResizerCouldNotResizeImage extends PetrKnap\Shorts\Exception\CouldNotProcessData implements ImageResizerException {}

final class ImageResizer {
    public function resize(string $image) {
        throw new ImageResizerCouldNotResizeImage(__METHOD__, $image);
    }
}

NotImplemented

Simple exception for prototyping purposes.

final class StringablePrototype implements Stringable {
    public function __toString(): string {
        PetrKnap\Shorts\Exception\NotImplemented::throw(__METHOD__);
    }
}

HasRequirements trait

Simple trait to check if requirements of your code are fulfilled.

final class ServiceWithRequirements {
    use PetrKnap\Shorts\HasRequirements;
    
    public function __construct() {
        self::checkRequirements(functions: ['required_function']);
    }

    public function do(): void {
        required_function();
    }
}

It should not replace Composers requires, but it could improve them and check suggests.

Testing

IlluminateDatabase helper

Simple helper which provides logic to test Illuminate\Database without Laravel mess.

$pdo = new PDO('sqlite::memory:');
$pdo->exec('CREATE TABLE tigers (id INTEGER PRIMARY KEY, name VARCHAR)');
$pdo->prepare('INSERT INTO tigers (name) VALUES (?), (?), (?)')
    ->execute(['Roque', 'Jasper', 'Gopal']);

PetrKnap\Shorts\Testing\IlluminateDatabase::createCapsuleManager($pdo)
    ->bootEloquent();

class Tiger extends Illuminate\Database\Eloquent\Model {}

assert(Tiger::count() === 3);

MarkdownFileTest interface + trait

The interface and trait let you automatically test code examples in a Markdown file like README.md.

final class ReadmeTest extends PHPUnit\Framework\TestCase implements PetrKnap\Shorts\PhpUnit\MarkdownFileTestInterface {
    use PetrKnap\Shorts\PhpUnit\MarkdownFileTestTrait;

    public static function getPathToMarkdownFile(): string {
        return __DIR__ . '/../README.md';
    }

    public static function getExpectedOutputsOfPhpExamples(): array {
        return [
            'some example' => 'has this output',
        ];
    }
}

By specifying the file path and expected outputs, the trait runs each code block and checks that its output matches, keeping documentation examples correct and up‑to‑date.
